[0002] The printer is one of the office equipment and is used in many places. The shaft core is one of the important components inside the printer. The printer shaft core is usually a long cylindrical rod.

[0003] At present, when processing the printer shaft core, the end of the printer shaft core needs to be polished. Before the polishing process, the printer shaft core needs to be manually taken and placed inside the polishing device. Due to the large number of printer shaft cores, the manual operation intensity is large during the repeated taking process, resulting in reduced polishing efficiency of the printer shaft core. Therefore, a printer shaft core polishing and unloading device is proposed. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a printer shaft core grinding and blanking device.

[0025] The utility model provides Figure 1-2 The printer shaft core grinding and feeding device shown in the figure comprises a hopper 1 and a feeding tube 2, the feeding tube 2 is fixedly installed at the bottom of the hopper 1, the bottom of the hopper 1 adopts a conical structure, the inner wall size of the feeding tube 2 matches the size of the shaft core, and the outer wall of the hopper 1 is fixedly provided with a mounting frame 3, and the mounting frame 3 can be installed on the grinding device so that the feeding tube 2 is aligned with the clamping station of the grinding device; baffle plates 4 are horizontally inserted on both sides of the feeding tube 2, and the baffle plates 4 are arranged on one side of the inside of the feeding tube 2 with an inclined surface, one side of the two baffle plates 4 extends to the outside of the feeding tube 2 and is provided with an elastic mechanism, and one side of the two baffle plates 4 is fixedly provided with a pull rope 5, and a pulling ring 6 is provided on the outer side of the bottom of the hopper 1, and the top two sides of the pulling ring 6 are fixedly connected to the bottom of the hopper 1 through telescopic tubes 7. The sides of the two pull ropes 5 away from the baffle plate 4 are fixedly connected to the two sides of the bottom of the pulling ring 6. The tube wall of the discharge tube 2 is fixedly provided with an inclined support rod 13, and the end of the support rod 13 is rotatably provided with a guide wheel 14. The pull rope 5 passes through the guide wheel 14. The guide wheel 14 can change the pulling direction of the pull rope 5, so that the pull rope 5 is pulled at 90°; the bottom of the hopper 1 is provided with a lifting mechanism for pushing the pulling ring 6 upward. The lifting mechanism pushes the pulling ring 6 upward so that the pull ropes 5 on both sides can be pulled at the same time, so that the ends of the two pull ropes 5 can pull the two baffle plates 4 outward at the same time. At this time, the printer shaft core inside the discharge tube 2 can be released, and then when the lifting mechanism does not push the pulling ring 6 upward, the baffle plate 4 blocks the falling printer shaft core under the action of elastic force to stop continuous feeding.

[0026] In order to enable the baffle plate 4 to have the function of elastic expansion and contraction, as Figure 2-3As shown, the elastic mechanism includes a fixed plate 8 and a spring 9. The fixed plate 8 is fixedly arranged on one side of the baffle plate 4. The spring 9 is symmetrically fixedly arranged between the side of the fixed plate 8 and the tube wall of the discharge tube 2. The spring 9 can apply elastic force between the fixed ring 8 and the discharge tube 2, so that the two baffle plates 4 support the printer shaft inside the discharge tube 2.

[0027] Finally, in order to be able to automatically push the pull ring 6 upwards, as Figure 1-2 As shown, the lifting mechanism includes a motor 10, a lifting cam 11 and a lifting block 12. The motor 10 is fixedly mounted on the side wall of the hopper 1, the lifting cam 11 is fixedly mounted on the output shaft of the motor 10, the lifting block 12 is fixedly arranged on the inner wall of the pull ring 6, and the lifting block 12 and the lifting cam 11 are arranged in corresponding positions. The operation of the motor 10 can drive the lifting cam 11 to rotate, so that the raised portion of the lifting cam 11 pushes the lifting block 12 upward, thereby pushing the pull ring 6 upward. When the raised portion of the lifting cam 11 is separated from the lifting block 12, the pull ring 6 automatically falls due to gravity, and the pulling force of the pull rope 5 on the material blocking plate 4 is released. The material blocking plate 4 blocks the falling printer shaft core under the action of elastic force.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
